domain of (3x+6)/(x^2-x-2)

domain

\frac{3 x + 6}{x ^{2} - x - 2}

x < - 1 or - 1 < x < 2 or x > 2

Interval Notation

(- \infty, - 1) \cup (- 1, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = 2, x = - 1

The function domain

x < - 1 or - 1 < x < 2 or x > 2

f (x) = \frac{8}{16 - x ^{2}}

f (x) = x^{3} - 3 x - 2

\frac{3 x ^{2} + x - 10}{5 x ^{2} - 27 x + 10}

\frac{x ^{2}}{x ^{2} - 9}

f (x) = \frac{( 1 - x )}{2 x - 1}
